I rented this incredible lace Temperley London Francine Gown for a black tie wedding I attended this past weekend. It was so comfy, like wearing pajamas (pretty much the opposite of all of the formal gowns I own now that my waistline and bust are growing). When with child, renting is definitely the way to go for formal events. Just be sure to size up (or two or three depending on how far along you are) and avoid anything that cinches at the natural waistline. I wish I could have kept this one (in a size smaller of course).
